Social networking site Meetup helps you find and join groups in your area that share a common interest, allowing you to share your mutual passions.

Boasting over 2 million users, there's sure to be a Meetup that matches your interests. It's completely free to join an existing Meetup group, but costs $12/month if you'd like to start your own Meetup group. If life on the 'net has got you craving some real social interaction, Meetup looks like a great way to find peers with common interests. Thanks Jarrod!
